Part 2: Client Program with ArrayList Create a second client program. This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…

Write a modeMaker function
Write a function modeMaker() that forms a closure such that the function it returns can be used with your reduce() function above to find the mode of an array. The mode of an array is the value that appears the most frequently (so in the $arr above, the mode is 5). To do this, you will need an array called $seen that keeps the count of times an element has been examined At the end of the reduce function, the $seen array should look like the following for the $arr above:
Array ( [10] => 1 [5] => 3 [3] => 1 [1] => 1 [2] => 1 [7] => 1 )
Note that the closure you generate should always be returning the current mode for what it has seen so far (so it will either be the current mode, or the new element passed in). The following is a start for modeMaker:
function modeMaker() { $seen = array(); return function($current, $new) use (&$seen) { // your code that uses $seen goes here }; } $mode =…

write a function 'keyValueDuplicates (obj) that takes an object as an argument and returns an array containing all keys that are also values in that object.
Examples:
obj1 = { orange: "juice", apple: "sauce", sauce: "pan" }; console.log(keyValueDuplicates (obj1)); // ["sauce"]
obj2 = { big: "foot", foot: "ball", ball: "boy", boy: "scout"};console.log(keyValueDuplicates(obj2)); // ["foot", "ball", "boy"]
obj3 = { pizza: "pie", apple: "pie" pumpkin: "pie"); console.log(keyValueDuplicates (obj3)); // []

- 1. Array Allocator Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.arrow_forward10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array.

- 8. Grade Book A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores: Test Score Letter Grade 90–100 A 80-89 B 70-79 C 60-69 D 0-59 Write a class that uses a String array or an ArrayList object to hold the five students' names, an array of five characters to hold the five students' letter grades, and five arrays of four doubles each to hold each student's set of test scores. The class should have methods that return a specific student's name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and his or her four test scores. It should then display each student's average test score and letter grade.

Your program must contain the class ticTacToe to implement a ticTacToe object. Include a 3-by-3 two-dimensional array, as a private member variable, to create the board. If needed, include additional member variables. Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move. Add additional operations as needed. (programming language C#)arrow_forwardFinding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run: Enter the number of elements of array 1: 7 Enter the elements of array 1: 10 12 13 10 14 15 12 Enter the number of elements of array 2: 5 Enter the elements of array 2: 17 12 10 19 12 The common members of array1 and array2 are: 12 10arrow_forward
